There is no limit other servers have more 500 cars, and shit ton of scripts, ex. All Day Role Play server have the most scripts known in FiveM and nothing is happening. It deepens on how much your PC can handle the more better PC the more the PC can handle.

it will be a ymap on the server that is not compatible with the new update, load in to the server and press F8 to get hte console window up and get ready to press F12 fast for a screen shot just before it crashes! it will say error with a XXXX.rpf.

You then need to do it again for the next ymap rpf file that makes an error etc… then disable those ymaps in your server.cfg, clear your server cache, clear your local game/PC cache and it will work
